The witness reads προφητείας in the phrase τοὺς λόγους τῆς προφητείας τοῦ βιβλίου τούτου, so the form is part of a nested genitive construction.

The lemma is προφητεία, a noun meaning prophecy or prophetic utterance, and this form keeps that lexical identity in genitive singular.

In this verse the genitive works with the article and neighboring genitives to describe the words being addressed, not to create an independent assertion about prophecy.

The clause tells the hearer not to seal the words of this prophetic book, because the time is near, so the genitive supports a reading where the utterance is treated as prophetic and publicly relevant.

For readers and teachers, the form helps express that the focus is on the book's prophetic words, while the command and reason remain the main point.

Do not derive a claim that the genitive alone defines the exact subtype of prophecy, the source of prophecy, or any theological gender meaning.
